during operation.
Use your unit as a blower for:
• Sweeping debris or grass clippings
from driveways, sidewalks, patios, etc.
• Blowing grass clippings, straw, or
leaves into piles, around joints, or between bricks.
Use your unit as a vacuum for:
• Picking up dry material such as
leaves, grass, small twigs, and bits of
paper.
• For best results during vacuum use,
operate your unit at high speed.
• Move slowly back and forth over the
material as you vacuum. Avoid forcing the unit into a pile of debris as
this can clog the unit.
• Keep the vacuum tube about an inch
above the ground for best results.

OPERATING TIPS
• While vacuuming or blowing debris,
hold the unit with the muffler side facing away from your body and clothes
(see OPERATING POSITION).
• To reduce the risk of hearing loss
associated with sound level(s), hearing protection is required.
• To reduce the risk of injury associated
with contacting rotating parts, stop the
engine before installing or removing
attachments. Do not operate without
guard(s) in place.
• Operate power equipment only at reasonable hours-not early in the morning or late at night when people might
be disturbed. Comply with times listed
in local ordinances. Usual recommendations are 9:00 a.m. to 5:00 p.m.,
Monday though Saturday.
• To reduce noise levels, limit the number of pieces of equipment used at
any one time.
• To reduce noise levels, operate power blowers at the lowest possible
throttle speed to do the job.
• Use rakes and brooms to loosen
debris before blowing.
• In dusty conditions, slightly dampen
surfaces or use a mister attachment
when water is available.
• Conserve water by using power blowers instead of hoses for many lawn
and garden applications, including
areas such as gutters, screens, patios,
grills, porches, and gardens.
• Watch out for children, pets, open
windows, or freshly washed cars.
Blow debris away safely.
• Use the full blower nozzle extension
so the air stream can work close to
the ground.
• After using blowers and other equipment, CLEAN UP! Dispose of debris
in trash receptacles.

BEFORE
STARTING
'_LWARNING:
ENGINE
Be sure to read the
fuel information in the safety rules
before you begin. If you do not
understand the safety rules, do not
attempt to fuel your unit. Call
1-800-235-5878.
FUELING
ENGINE
,_LWARNING:
Remove fuel cap
slowly when refueling.
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good
quality 2-cycle air-cooled engine oil.
We recommend Craftsman brand oil.
Mix gasoline and oil at a ratio of 40:1
(A 40:1 ratio is obtained by mixing 3.2
ounces of oil with 1 gallon of unleaded
gasoline). DO NOT USE automotive oil
or boat oil. These oils will cause engine damage. When mixing fuel, follow
instructions printed on container.
Once oil is added to gasoline, shake
container momentarily to assure that
the fuel is thoroughly mixed. Always
read and follow the safety rules relating to fuel before fueling your unit.
IMPORTANT
Experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract moisture which leads to separation and
formation of acids during storage.
Acidic gas can damage the fuel system of an engine while in storage.
To avoid engine problems, empty the
fuel system before storage for 30 days
or longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh
fuel next season.
Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.
Fuel stabilizer is an acceptable alternative in minimizing the formation of
fuel gum deposits during storage.
Craftsman brand oil is already blended
with fuel stabilizer. See the STORAGE
section for additional information.
STOPPING YOUR ENGINE
• To stop the engine, move the throttle
lever to the STOP position.
STARTING
THEENGINE
_LWARNING:
You MUST make sure
the tubes are secure before using the
unit.
• Fuel engine. Move at least 10 feet (3
meters) away from the fueling site.
• Hold the unit in the starting position
as shown. Make sure the blower end
is directed away from people, animals, glass, and solid objects.

• Loss of power. See MIXTURE ADJUSTMENT (L or H) under adjusting procedure.
There are two adjustment screws on
the carburetor. The low speed adjustment screw is marked with the letter L,
and the high speed adjustment screw
is marked with the letter H. The throttle
lever is used to control engine speed.
The throttle lever can be placed in one

to explain the emissions control system warranty on your lawn and garden
equipment engine. All new utility and
lawn and garden equipment engines
must be designed, built, and equipped
to meet the stringent anti-smog standards. Sears must warrant the emission control system on your lawn and
garden equipment engine for the periods of time listed below provided there
has been no abuse, neglect, or improper maintenance of your lawn and
garden equipment engine. Your emission control system includes parts
such as the carburetor and the ignition
system. Where a warrantable condition
exits, Sears will repair your lawn and
garden equipment engine at no cost to
you. Expenses covered under warranty include diagnosis, parts and labor.

MANUFACTURER'S
WARRANTY
COVERAGE: If any emissions related
part on your engine (as listed under
Emissions Control Warranty Parts List)
is defective or a defect in the materials
or workmanship
of the engine causes
the failure of such an emission related
part, the part will be repaired or replaced by Sears. OWNER'S WARRANTY RESPONSIBILITIES:
As the
lawn and garden equipment engine
owner, you are responsible for the performance of the required maintenance
listed in your instruction manual. Sears
recommends that you retain all receipts covering maintenance on your
lawn and garden equipment engine,
but Sears cannot deny warranty solely
for the lack of receipts or for your failure to ensure the performance of all
scheduled maintenance.
As the lawn
and garden equipment engine owner,
you should be aware that Sears may
deny you warranty coverage if your
lawn and garden equipment engine or
a part of it has failed due to abuse, neglect, improper maintenance,
unapproved modifications, or the use of
parts not made or approved by the
original equipment manufacturer.
You
are responsible for presenting your
lawn and garden equipment engine to
a Sears authorized repair center as
soon as a problem exists. Warranty
repairs should be completed in a reasonable amount of time, not to exceed
30 days. If you have any questions
regarding your warranty rights and responsibilities, you should contact your

center. CONSEQUENTIAL

caused by the failure of a warranted
part still under warranty. WHAT IS

or modified parts can be grounds for disallowing a warranty claim. Sears is not
liable to cover failures of warranted
parts caused by the use of add-on or
modified parts. HOW TO FILE A
CLAIM: If you have any questions regarding your warranty rights and responsibilities, you should contact your
